Here's a look at some of the top health news being talked about around the U.S. and the world today:

• Could it be the perfect marketing strategy? Get a vasectomy just in time for March Madness and you'll have the perfect excuse for staying home and lounging on the couch watching the game for a few days. Turns out, more urologists are offering March Madness deals - even sweetening the offer with pizza and mugs - to get men to get the procedure, ABC News reported.

• The envelopes that held the fates of University of Michigan medical students were handed out yesterday during Match Day, the day every year when graduating medical students around the country simultaneously learn where they will complete their post-graduate training.

As the Los Angeles Times put it, "the students request the type of specialty they want to practice, as well as their top preferences for where they'd like to train. Overall, the news Thursday wasn't great for consumers." That's because all these specializing students likely points to a continued shortage of primary care physicians into the future.

It's not all bad news for health care. However, one director of medical student education at the University of Maryland in Baltimore, said he was encouraged by an increase he saw in students going into primary-care specialties, the Baltimore Sun reported.

• Tuberculosis cases are at historic lows in the United States, but strains of drug-resistant TB are a growing concern throughout other parts of the world, the Los Angeles Times reported.

• More children are falling in the extremely obese category, according to a large-sale study that lends additional pressure behind recent campaigns to combat childhood obesity, Time reported.
